Which type of powder has been shown to be more sensitive than others in latent print processing?

Aluminum powder has been shown to be more sensitive than other types of powders in latent print processing due to its finer particle size and reflective properties. These characteristics allow aluminum powder to adhere more effectively to the oils and moisture in latent prints, making the details of the fingerprint more visible. The ability of aluminum powder to reveal prints on various surfaces, especially smooth ones, is enhanced because it can collect even the smallest traces of fingerprint residue. This increased sensitivity is particularly beneficial when working with challenging surfaces or in conditions where other powders may not perform as well. Therefore, the choice of aluminum powder for latent print enhancement is often favored in forensic applications where clarity and detail are critical.
